Topic: 91 hatch STD. 10's under 400whp? (Read 16000 times)

PhilStubbs · « **on:** October 06, 2010, 03:08:46 PM »

Is it possible? I have a 91 STD hatch with a vitara block and turbo setup worth about 350-375whp. Are 10's possible? I have a bigger turbo I could use and get well over 400whp but I'm trying to stay away from that.

I'm guessing. 23" tire. Maybe bigger?

you dont remember the nasty gold hatch gutted with big holes in the hood?, cant remember the user name, east coast member though

PhilStubbs · « **Reply #2 on:** October 06, 2010, 03:58:04 PM »

Sounds kind of familiar, don't remember it enough to base a plan of action around it.

jarebear667 · « **Reply #3 on:** October 06, 2010, 03:58:54 PM »

it was built on the cheapest of cheap, someone will post it up. it was on a holset.

Dr. D series

Did 10's with like 330whp

But I will let you know he could drive the shit out of that car!

jarebear667 · « **Reply #5 on:** October 06, 2010, 03:59:26 PM »

and i think he got deep into the 11's with low 200 hp.

PhilStubbs · « **Reply #6 on:** October 06, 2010, 04:12:20 PM »

I'm using a cdm 50 trim that I rebuilt. I have been daily driving it at 15 psi for a long time with no issues. I just don't want to push it past 20psi. It's good for about 375whp at 20psi. I have a real Garrett 60-1 I can use if I need more power, but this is for a GRM $2011 build so I am trying to stay away from something expensive.

Easy way to find out.

PhilStubbs · « **Reply #8 on:** October 06, 2010, 04:37:49 PM »

I plan to find out, I'm 99% sure I will run this setup, I just really want to run high 10's for this race. I was hoping someone else has done it

chris · « **Reply #9 on:** October 06, 2010, 04:46:02 PM »

The gold hatch ran 10.30's with 430

danz · « **Reply #10 on:** October 06, 2010, 05:28:42 PM »

its easily doable with enough weight reduction and good driving.

good driving being the part you either got, or you dont.

And got suspension and alignment helps. :yes:

Well dr.d did it on a totlay mismached suspention setup. And I think he did it with a few blown shocks too. If I rember right he ran like a hi 10 with 330whp ish. But then he did a bunch more work and ended up with like 430 like chris said.

PhilStubbs · « **Reply #13 on:** October 06, 2010, 11:20:00 PM »

This sounds well within my reach for this car then. I have been researching drag suspension and I think I can get that car pretty light. I'm not a horrible driver but I have a lot more street racing experience over actual track experience.

danz · « **Reply #14 on:** October 07, 2010, 12:25:12 PM »

get 24.5's the newer the better for slicks. trust me spinning down the track on slicks sucks huge, such a waste of power...

throw some VX's on the rear and pump em up to 50psi

the lighter the wheel/tire combos the better of course. no rear disc or integra brake upgrades that shit is so gay.

get an LSD, just to keep the tranny alive.

flat foot shifting helps a lot.

seat time.

put the roll bar in right off the bat.

try removing the hood for more weight reduction.

oh and dont forget to upgrade your shitty STD axles because when they break, and they will, you will have a hard time finding another one.

PhilStubbs · « **Reply #15 on:** October 07, 2010, 01:08:24 PM »

LSD is out of the question, it just won't fit the budget.

It seems that the hood would be more beneficial as aerodynamics than gone for weight. I guess I should add that I will be making a fiberglass hood for the car. I am considering removing the rear hatch for weight reduction.

I plan to make it to a few test n tune nights before the actual event.

I have extra axles that are non STD.

I have no intentions of touching the brakes. The turbo will be too big to really be good in the auto-x. No sense in wasting tire money on brakes that won't do me any good.

My wife sells tires wholesale and said she can get some toyo slicks for $130 each. I think I will just get them new. That might be 23" though. I will have her check again.

I do plan to cage it. The cage is considered a safety item and doesn't come out of the budget.

I appreciate the info, I hope I don't come off in that post as sounding like I know it all. Just laying out my plans as people bring up important points

danz · « **Reply #17 on:** October 07, 2010, 01:19:51 PM »

the tranny wont hold up long on the stock diff and when the diff goes the tranny case usually goes with it. just to warn ya. it might last for a while it might pop on the first launch.

the short game is where it all happens. if the launch is soft and slow the pass will be just as crappy.

got a link to the toyo slicks?

dvst8r · « **Reply #18 on:** October 07, 2010, 01:31:16 PM »

Weld it.

Trevor72 drives his welded diff almost daily, and he is just a little guy (well compared to the rest of us in the NW and NW Canada area) His vitara hx-35 setup makes ~400whp.

I was just about to sudjest welding the diff my self.

In for the links on the Toyo slicks. Curious to see if they are the same or similar to the 4 slick I have. A08's or something like that. $:-\$

PhilStubbs · « **Reply #20 on:** October 07, 2010, 01:36:53 PM »

Welding it crossed my mind. I just don't want to kill the auto-x time. I also considered welding up a spare diff and swapping it after the auto-x.

No link to the slicks myself. Her company is a toyo dealer to tire stores, they don't have any web stuff available to the general public.

danz · « **Reply #21 on:** October 07, 2010, 05:10:33 PM »

maybe just keep your eyes open for a used OBX. that would be the budget orientated thing to do.

but you never know it might hold up. might be a good idea to go for 23s or 22's in that case tho. easier on the drive train.

dvst8r · « **Reply #22 on:** October 07, 2010, 07:49:49 PM »

Seems to me you would be faster at auto x with a welded diff, then an open one. Be able to actually put the power down instead of just spinning the inside tire.

Joseph Davis · « **Reply #23 on:** October 07, 2010, 07:56:17 PM »

NA guys run 10's off of 250 whp. What do they know that you do not?

weight reduction, aero, how to drive, proper gearing, weight reduction, and more weight reduction?

Do a few lines of coke a day and ull get the weight down

The spool in the drag car makes normal three point turns impossible, with a driver that weighs in as three Trevors. 3-4 guys follow the car around and push on the ass end of the car to hop it around tight corners.

Glad to see you found your voice.

I weigh in at just shy of an actual two Trevor's, and have no issues driving that car, or even slow speed parking it, in a tight lot. If anything little Trevor's have more issues trying to muscle it.

I had a '79 civic, with the goldwing pistons, and 4 dellorto carbs, koni inserts ect... Going to a welded diff in that made me almost a full second quicker on the local boundary bay airport auto x.

Eh, either soft 24.5" slicks change the dynamic or the frozen tundra of Canadastan helps you out.
